Abstract:

The Severe Plastic Deformation (SPD) is an effective approach for producing bulk nanostructured material. Equal Channel Angular pressing (ECAP) processes provide an efficient procedure for achieving ultra fine grained material with excellent mechanical properties. The objective is to achieve high and homogeneous deformation in the work piece. In this work an optimized design of the channel die is presented which improves deformations obtained in materials using standard dies. This is a very useful process which can help in the reuse of bulk materials. It can convert the used bulk material to Ultra fine grained material. Ultra-fine grained materials exhibit superior mechanical properties such as high strength and ductility. In this work, three dimension finite element of ECAP process was carried out for Billet Material Copper with channel angle of 120° for Strain harding Copper using Forge 2007 software. The Simulation results clearly depict the Evolution of Strain on body of work piece. The FE simulation greatly help to design the experimental condition to produce good material die for forging. The process parameter of ECAP influences the effect on properties of material. In the present study FEM modeling of ECAP process using Copper for 10 mm round billet is attempt the effect of various process viz. channel intersection angle, friction at die billet and punch velocity are studied. The FE simulations greatly help to design the experimental condition to produce good quality products in manufacturing industries.
